repotting orchids thinking "outside the box"

[Mo Boggie]

I will setting up an outdoor portable greenhouse, and decided to repot all my orchids. I've decided to attempt some unconventional repotting; I'm will not be using slabs or pots. I purchased Nylon Poly-Mesh Net Bags, that are somewhat larger than what is used for garlic. I plan to place Styrofoam in the center and med bark around the outer circumference of the root ball. I will hang them using hooks. My hope is that mesh net will allow plenty of air circulation, & reduce my overwatering. The greenhouse will be covered in aluminet shade cloth. Any thoughts or suggestions will be appreciated . Thanks
